The new MultiCart is designed with versatile coaches and teaching pros in mind. The 100-ball capacity MultiColor Baskets are color-coordinated to match the red, orange, and green colors of our 10andUnder tennis balls, boundary lines. We also include a yellow basket for your regular tennis balls as well. The complete Multicart Teaching Cart includes 4 MultiColor Baskets as shown, plus one Wire Storage Tray. The MultiCart also features our signature 4-inch screw-in wheels. Each MultiColor Basket holds approximately 100 balls. Use them to easily organize your color-coordinated transition balls for 10andUnder Tennis programs. To save on storage space at larger facilities, the carts stack together (with MultiColor Baskets removed) just like store shopping carts. Assembly is quick and easy without tools.
